XR-096
Quad Programmable Bipolar JFET
Operational Amplifier
GENERAL DESCRIPTION
The XA-096 monolithic circuit contains four indepen-
dently programmable JFET operational amplifiers in a
single IC package. Each of the four op amp sections on
the chip has its own external bias terminal; thus its per-
formance characteristics and power dissipation can be
independently controlled, without effecting the other op
amp sections on the chip. The respective bias-setting
resisters, RSETt connected to the programming termi-
nals of the circuit allow one to trade-off power dissipa-
tion for slew-rate, without sacrificing the gain-
bandwidth product of the circuit. These individual bias
terminals can also be used to switch the op amp sec-
tions "on" and "off", and thus, multiplex between vari-
ous op amp channels on the same chip.

Note 1: For Supply Voltage less than ± 15V, the absolute maxi-
mum input voltage is equal to the supply voltage.
Note 2: The output may be shorted to ground or to either sup-
ply. Temperature and/or supply voltages must be lim-
ited to ensure that the dissipation rating is not exceed-
ed.

SYSTEM DESCRIPTION
The XA-096 is a quad independently programmable
JFET input operational amplifier featuring extremely
high input resistance, low input bias and offset current,
large common mode voltage range, and large output
swing range. Unity gain bandwidth is 3 MHz, and slew
rate is 13V/p.S. The devices are unity gain compen-
sated.
Each of the form amplifiers may be independently
"programmed"-rebiased-by connecting a resistor from
the bias adjust pin to the positive supply. Bias current
may range up to 400 /LA, thus affording the designer
flexibility along the power consumption/speed curve.
